"We are coming together for a vigil. A vigil for Leelah, a vigil for a life that should have never ended in such a tragic way," the event reads.

A suicide note reportedly left by Alcorn caused a buzz on social media after it appeared on Tumblr the night of the teen's death.

Born Joshua Alcorn, the 17-year-old died Sunday after being hit by a tractor trailer in a suburb of Cincinnati. The note posted to the social media site prompted police to investigate the death as a suicide.

In the note, Alcorn reportedly wrote about the difficulties she faced growing up.

"The life I would've lived isn't worth living in… because I'm transgender," read a portion of the note, according to ABC News. "I could go into detail explaining why I feel that way, but this note is probably going to be lengthy enough as it is. To put it simply, I feel like a girl trapped in a boy's body, and I've felt that way ever since I was 4," the note read.

Another passage from the note was posted to the event page for the Orlando vigil, asking others to "fix society."

"The only way I will rest in peace is if one day transgender people aren’t treated the way I was, they're treated like humans, with valid feelings and human rights," Leelah reportedly wrote. "Gender needs to be taught about in schools, the earlier the better. My death needs to mean something. My death needs to be counted in the number of transgender people who commit suicide this year."

In addition to the vigil in Orlando, groups are gathering in Ohio and around the country to mourn Alcorn's death and raise awareness for transgender and other LGBT issues.
